UNITED STATE-"s PATENT. OFFICE.,

JAMES SOLOMON MCKEZIE, OF MIAMI, FLORIDA.

SPECIFICATION forming part of Letters Patent No. 634,473, dated October 10, 1899. application Hed March 17, 1898. Serial No. 674,207. (No model.)

of Florida, have invented certain new and.

useful Improvements in Dust-Guards for Railway-Gars; and I do declare the following to be a full, clear, and exact description of they invention, such as will-enable others skilled in the art to which it appertains to make and use the same.

The invention relates tov an improvement in dust and cinder guards for the windows of railway-cars.

The object of the invention is to provide a simple and inexpensive device of this character which may be easily attached to the windows of cars now in general use and which will effectively catch the dust and cinders which workther way between the lower rail of the sash and the window-sill. Y

With this objectin view the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure 1 is 'a perspective view taken from the outside of the car, showing my improved dust and ciuder guardie,`

5 denotes the dust and cinder pan, which l is approximately semicylindrical in crosssection and snugly tits the inside faces ofthe' side frames 2.

7 denotes a slide on the inner beaded face of the pan to permit of access to the thumb-v button S on the lower rail of the blind, and 9 denotes aV similar slide to permit the sashlock to be reached and manipulated.

10 denotes a longitudinal brush-shaft loosely journaled in bearing-brackets 1l 11, xed in the end walls 6 6. "yA flexible cord 12 is wound around the shaft in one direction, and asimilar cord 13 is wound around the shaft in 'a reverse direction, both cords passing through suitable orifices in the pan and provided with grip-knobs 15, so that by alternately'drawing said cords inwardly the shaft will be rotated Fig. 3 is a transverseY in opposite directions. This shaft is provided with a circular brush 16, the diameter of which isgreater than the space between the lower sash-rail 3 and the inside face of the pan, whereby when in position the fibers `or tufts of the brush press against the lower sash-rail 3 and its pane of glass as well as lthe inner face of the pan. It is evident, therefore, that should any dust or cinders Work between the lower edge of the rail 3 and the sill and thence upwardly they would be' caught by the brush and be prevented from escaping into the car.

17 denotes a removable diaphragm or false bottom supported by the cross-braces 18 1S, the projecting edges of which rest against the curved parallel sides of the pan in such a manner as to leave passage-Ways or openings 19 between the false bottom 17 and the-sides ofthe pan, as shown in Fig. 1, so that the dust and cinders arrested by said brush may p ,be dislodged therefrom 4and drop into the bottom of the pan by rotating the brush by the operating-cords 12 13. n

Thel operation of the device is very simple and will be readily understood from the preceding description taken in connection with the accompanying drawings, from which it will be seen that particles of coal-dust and cinders which may enter under the windowsash will be caught by the brush and be dislodged therefrom by its rotation and fall through the passage-ways 19 into thebottom of the pan.

The pan may be provided with an opening 20 in its end, through which the accumulated dust and cinders may be dumped by removing the pan from its position and tilting the end with the opening downward.

Having thus described theinvention, what is claimed,'and desired to be secured byLetters Patent, is-

1. A dust and cinder guard for railway-cars comprising a semicylindrical pan provided with a diaphragm the width of which is less than that of the pan, whereby passages' are formed between its edge andthe sides of the diaphragm, and a rotary brush the diameter of which is greater than the width of the diaphragm, whereby, when in'position, the brush will be pressed against the lower rail of the window-sash in position to catch any dust and einders which may enter the ear under said rail, substantially as and for the purpose set forth.'

2. A dust and einder guardfor railway-oer Windows comprising the semieylindrioal pan provided with slides 7 and 9, and the removable diaphragm 17, horizontally arranged in said pan so as to form passage-Ways 19 '19 between the parallel edges of said diaphragm and the sides of the pan; in combination with a rotary brush adapted to press against the inner side of the lower' sash and catch any cnders or dust which may Work up under the lower edge of the seme, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence otwo subscribing Wit; nesses.
